Abstract
An N bit sub-binary radix digital-to analog converter (DAC) includes a radix conversion module that converts an m bit digital input signal to an N bit sub-radix DAC code. A ladder module having NL bits has a plurality of first circuit elements corresponding to first respective bits of the N bit sub-radix DAC code. A segment module having NS bits has at least one second circuit element corresponding to second respective bits of the N bit sub-radix DAC code. N>m, and N is the sum of NL and NS.
